The prevalence of depression in people following limb amputation: A systematic review and meta-analysis.

Objective: To estimate the prevalence of depression in people with limb amputation. Additionally, factors affecting the prevalence or pattern of depression following limb amputation were explored.

Methods: Systematic literature search to identify all relevant studies assessing prevalence of depression following limb amputations was conducted through following databases: PubMed/ MEDLINE, Scopus, Embase, and Web of Science. Search period was since inception of database till December 2021. Meta-analyses using random-effects model were conducted to estimate pooled prevalence of depression.

Results: A total of 61 studies comprising 9852 limb amputees were included. Pooled prevalence of depression following limb amputations was 33.85% (95% CI: 27.15% to 40.54%), with significant heterogeneity (I = 98.57%; p < 0.001). Sub-group meta-analysis showed that pooled prevalence of depression was significantly higher in studies conducted from middle-income (45.31%, 95% CI: 28.92% to 61.70%) as compared high income countries (28.31%, 95% CI: 23.97% to 32.64%). Greater activity restriction, amputation-related body image disturbances, social discomfort, perceived vulnerability regarding disability, and avoidant coping style were commonly reported factors associated with greater depression symptomatology. Whereas, good perceived social support, and use of more active coping strategies were commonly reported protective factors.

Conclusion: About one-third of all limb amputees suffered from clinically significant depression. This emphasizes need to sensitize health care professionals involved in providing care to people following limb amputation regarding the importance of periodically screening this vulnerable group of patients for depression and liaising with psychiatrists. Further, addressing risk factors identified in this review could help in reducing the rates of depression post-amputation.
